Hyperbolic formulations of General Relativity with Hamiltonian structure
, 2010 With the aim of deriving symmetric hyperbolic free-evolution systems for GR that possess Hamiltonian structure and allow for the popular puncture gauge condition we analyze the hyperbolicity of Hamiltonian systems.

Toward a Consensus Characterization Protocol for Organic Thermoelectrics
Advanced Materials, EarlyView.We advocate a common consensus on accurate and standardized reporting of performance metrics in the field of organic thermoelectrics. We summarize prevalent issues in the literature and propose a pre‐submission checklist to support the publication of reproducible results.

Abstract and Applied Analysis, 2013 We investigate an H1-Galerkin expanded mixed finite element approximation of nonlinear second-order hyperbolic equations, which model a wide variety of phenomena that involve wave motion or convective transport process.

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Electronic Journal of Qualitative Theory of Differential Equations, 2014 In this paper, we consider the Dirichlet problem for second-order hyperbolic equations whose coefficients depend on both time and spatial variables in a cylinder with edges. The asymptotic behaviour of the solution near the edge is studied.

Second-order hyperbolic Fuchsian systems. Gowdy spacetimes and the Fuchsian numerical algorithm [PDF]
, 2010 This is the second part of a series devoted to the singular initial value problem for second-order hyperbolic Fuchsian systems. In the first part, we defined and investigated this general class of systems, and we established a well-posedness theory in ...

Pattern Formation in Non‐Equilibrium Architected Materials
Advanced Materials Technologies, EarlyView.This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.
